1. Transform japanese sentence between different format(kana,kanji,romajin)
2. Mark pronunciation to kanji
3. Word Segmentation ( Need More Test )

const kakasi = require("kakasi");

(async()=>{
	const sentence =  "夢はジュエル　誰もひとつずつ　胸に抱きしめて";
	const senArr   =  ["夢はジュエル","誰もひとつずつ","胸に抱きしめて"]
    
	// -1.Transform->  
	let convertResult = await kakasi.toHira(sentence);
	console.log(convertResult.result)
	//  ゆめはじゅえる　だれもひとつずつ　むねにだきしめて

	// -2.Mark->
	let markResult = await kakasi.markKana(senArr);
	console.log(markResult.result)
	//  夢(ゆめ)はジュエル　誰も(だれも)ひとつずつ　胸(むね)に抱き(だき)しめて
  
	// -3.Separate-> 
	let sepResult = await kakasi.separate(senArr);
	console.log(sepResult.result)
	//  夢 は ジュエル 誰 もひとつずつ 胸 に 抱 きしめて
  
})()

Transform

const kakasi = require("kakasi");

(async() => {
    let result = await kakasi.toHira("夢はジュエル　誰もひとつずつ　胸に抱きしめて")
    console.info(result);
})()

(async() => {
    let result = await kakasi.markKata("夢はジュエル　誰もひとつずつ　胸に抱きしめて",'[',']',true)
    console.info(result);
})()

// MarkResult {

Knowledge

Just skip this section if you already know abot kanji,kana,hiragana,katakana and romajin.

kanji

Kanji ,or kan'ji, are the adopted logographic Chinese characters that are used in the modern Japanese writing system along with hiragana and katakana.

e.g

夢はジュエル -only the kanji-> 夢

誰もひとつずつ -only the kanji-> 誰

roma(Roman alphabet) <=> Latin alphabet

Mainly as Japanese , Korean pronunciation notes, similar to the English phonetic symbols.

e.g

夢はジュエル -marked with roma -> 夢(yu me)は(wa)ジュエル(ji yu e ru)

kana & hira(hiragana) & kata(katakana)

Kana (仮名) are syllabic Japanese scripts, a part of the Japanese writing system contrasted with the logographic Chinese characters known in Japan as kanji (漢字).

There are three kana scripts: modern cursive hiragana (ひらがな), formerly known as a women's script; modern angular katakana (カタカナ); and the old syllabic use of kanji known as man’yōgana (万葉仮名) that was ancestral to both. Hentaigana (変体仮名, "variant kana") are historical variants of modern standard hiragana.

In modern Japanese, hiragana and katakana have directly corresponding character sets (different sets of characters representing the same sounds).

e.g

#kana#

夢はジュエル -only the kana-> はジュエル

誰もひとつずつ -only the kana-> もひとつずつ

#hiragana#

夢はジュエル -only the hira-> は

誰もひとつずつ -only the hria-> もひとつずつ

#katakana#

夢はジュエル -only the kata-> ジュエル

誰もひとつずつ -only the kata-> NO_KATA_HERE
